To all whom it may concern.

Be it known that I, JOHN BRIGKEN a subject of the Emperor of Russia, residing at Chicago, in the count of Cook and State of d a certain new and useful Improvement in Calculating-Machines, of which thefollowing' is a specification;

My invention relates to calculating machines --particularly those which an associated with a t pewriter. A good example of this classv o machine is shown and described inithe' issued patent to John C. Wahl,

. No. 893,719; dated July 21, 1908.

My ipresent machine has some of its parts similar in structure to the machine described ii the above-cited patent, and has the same general mode of operation, viz.,- on the carriage ofthe typewriter is mounted a totalizer in which numbers are inserted .s-erz'atim by an actuating mechanism rigid with the typewriter frame.

While my actuating mechanism is similar in art that shown in the above cited We. l patent, the totalizer and carrying mechanism constituting my present invention are a wide departure from the Wahl structure.

One of the objects of my invention is to provide a calculating machine having but a single carrying mechanism, regardless of the number of totalizers which are employed. Each totalizer consists ofbut a single set of gear wheels which are provided with the customary number Wheels and a mechanism to transfer the tens from one gear to another is located in the actuator. This transfer mechanism is adapted .to coiiperate with any totalizer so that in the case of a calculating machine employing a plurality of totalizers, but one transfer mechanism is required for the plurality instead of havin an individual transfer mechanism associate with each totalizer as is the usual practice.

A further object of my invention is the provision of an improved form of actuating mechanism which is so interlocked with the transfer mechanism as to prevent overthrow of the latter. a

A further object of my invention is the provision of improved means to eliminate the spiral eiiect occurring whenthe carrys ae mmmmm. Patented Mar. 23, 1920.- Application sled December-15,1918. sci-an n. 806,821. A

.A further object of my invention s the provision of means to prevent actuation of the first transfer pinion when the; tqtaliizer is violently returned to zero.

These and further objects of my invention will be disclosed and referred to hereafter in y the specification and claims.

I shall divide the description of my invention into several heads, and describe the several mechanisms necessary to form the complete machine separately.

First-The totalizer.

The totalizer consists of two side plates 10 and 11, which are mounted on a truck 12, connected to and moving with the typewriter carriage 84. These plates are held the proper distance apart by shafts 13, 14 and 15, secured rigidly between the plates. The side plates 10 and 11 are dovetailed to be supported on the corresponding dovetail on the truck 12 (see Figs. 2 and 8). A latch 16 pivotally mounted-on a stud 17 in the side plate 11 and controlled by a finger iece 18 mounted on a stud 19 in the same si e plate engages the beveled surface on the back 0' the truck 12, thus serving to hold the toline of talizer rigid at an desired place on the said t a. tata ly mounted. on a shaft 15 are he. 6 g gearsQO each of which is provided with two carrying teeth 21. Ro tably mounted on the shaft 14 isa set of i e-g'eai' '86 which serve to transmit the motioii of the carrying gears 20 to a set of gears 22, rigid] attached to the number disks 23, these isks and gears being rotatabty. mounted on the shaft 13.

A set of division plates 87 supported on the shafts l4 and 15 setteto separate adjation to nuiiiber disks in adjacent places.

"A sifitabie'oover 24 having a window serves to protecttheinterioi of the totalizer and mask the numbers on the disks except the ones opposite the'window 25.

Pivotaliy inountediat 26 between the side plates 10 and 11 is 'a universal lock 27 havmg a 'cam28 attending the entire space betweenthe side plates 10 and 11, and adapted to en"'gsa11 oftlie carrying gears 20. it spriii '129 between the lock 27 and a bar 90 extending between the side plates serves to maintaiiilthe lock 27 in the position shown iniFigL' 2.

he caiiying' gears 20 have twent teeth and two carryin"teeth2-1. These carrying teeth are" in a diei'ent lane from the gear 20 itself, but are ri' y' attached thereto. Numbers are inserts in the totalizer sewat'im b" aj'master wheel 30 rotatably mounted in tlhe framework, thetotalizer escaping one step to the left after theirise'rtion f each digit of the number by the master wheel. The lock 27 is removed from its contact with the carrying gears 20 during the inscrtion of each number and the master wheel 30 is rotated by operation of numcralkeys 32 by means .which will afterward be described.

SccmztZ--The actuator.

As before remarked the actuator is smurwhat. similar-to that shown in the cited patent to Willll. Reference to Figs. 1 and 2 will'show that a pull rod 31 connects each of the ty ewriter numeral keys 32 to a cam she e piece 33, rotatably mounted on a shit i 34., in the framework. Operatibh of the typewriter key results in the diiwnitard motion of 'the pull rod 31, and

consequent rotation in a counter clockwise direction of the cam 33. I

I wish now tocall attention totwo functions of the cam 33. Rotation of the cam first results in some preliminar operations such as placing'the actuator an tctalizer in a position to permit differential rotation of counter clockwise direction, the engagement of the cam 35 with the roller 36 results in clockwise rotation of the rock shaftuntil the roller 36 has traveled tothe concentric sun face of the cam 35. Rigid with the rock shaft 38 is a. helical cam 39 (best'shown in Fi 1) operatin in a slotO in a piece t1 slic ably mounte in the framework. On a shaft 42 rotatably mounted in the framework, which shaft I shall hereafter call the sector BllitfQiSlIiOill'lf/Gd a sector 43swinging about a pivot 44. This sector 43 is so mounted on the ivot'44 in a block 45 rigid with the sector shaft 42 that it has no rotation in relation to the sector shaft. 42 but may have motion in a plane parallel to said shaft about its pivot 44. The normal position of the sector 43 is the position shown in Fig. 1. viz., out of engagement with master wheel gears presently to be described. Rotation of the rock shaft 38 and of the helical cam 40 rigid with it results in the shifting of the sliding piece 41, Fig. 1, to the left, and consequent movement of the sector 43 to a position )erpendicular to the sector shaft 42.

Thus er I have described oneof the pre liminary operations necessary for a rotation of the'ninster wheel. However, there is another preliminary operation which "it will be best to describe at this point, viz., the unlocking of the master wheel and carrying gears 20 and the locking of the totalizer to the actuator framework during the rotation of the master wheel 30.

Fulcrumed on'the shaft 46 in the framework is a master dog 47. An arm 48 ri id .with the rock shaft 38 has a roller 49 which engages a slot 50 in the tail of the master dog 47. The master dog is shown in its normal position in Fig. 2, and reference thereto will disclose that the slot 50 has in; lower portion concentric with the rock shaft 38, and its upper portion approximately vertical. From this it follows that rotation of the rock shaft 38 in a clockwise direction will result in rotation of the master dog 47 in a clockwise direction about its fulcrum 46.

- w The-upper'end of the master dog has three distinct functions. First,'the' cam '51 dogs the teeth of the master wheel 30. Second, a fork 52 engages the lock 27 withdrawin .thecam' 28 from the carrying gears 20 o the -tota, liz"er. Third, a tooth 53 engages between the teeth of arack 54 rigidly mounted to the' truck 12; thus locking the truck rigid to the actuator'frainework as long as the dog 47 is in its displaced position. -It will be remembered that the operation of 'any transfergears which will be referred to hereafter.

- I will now describe the means by which the master-wheel 30 is rotated the'number of teeth depending on the numeral key actuated." j a Loosely mountedon the shaft 34 is a series of necks 55, one for each cam 33. Rigidlymounted ineach gooseneck 55 is a pin 56 which cotiperates with a slot 57 in the -'-cam 33. Rotation of the cam 33 "will first rotate therock shaft 38 until the roller} 363s onthedead surface of the cam 35', then the right side of the slot 57 will engage thepin 56, and carry the gooseneck'with it during the remainder of the motion ofthe cam Rigidly mounted on the sector shaft 42 is aseries of arms 58, having rollers 59 mountcdthereon, which arms are engaged by the goosenecks 55 as shown in Fig. 2 and rotated thereby until said rollers 59 are in the concentric-slots of the goosenecks. These arms 58 are so arranged on the sector shaft 42 that the actuation of different goosenecks will resultin different degrees of rotation of the said shaft. There is a gooseneck 55- for each numeral key 32 of the typewriter, and the arms are so arranged that actuation of any key will result through the action of its associated gooseneck on an arm 58 in rotation of the sector 43 the required amount.

The sector 43 may engage with the gear 60,'sl'idably but non-rotatably mounted on a shaft 62 rotating in the framework (best shown in Fig. 3). The master wheel 30 is rigid with the shaft 62 and has a yoke 92, arranged to engage a similar yoke 93 rigid with the gear 60. Thus any rotation of the gear 60 results in an equal rotation of the master wheel 30. Meshing with the gear 60 is a gear 61 rotatably but non-slidably mounted on a shaft 63. The gears 60 and 61, and the shaft 63 correspond in position and functions to the gears 52 and 56 and the shaft 54 in the cited'patent to Wahl.

Reference to this patent will show clearly how the shifting of the shaft 54 therein (corresponding to the shaft 63 in Fig. 3 of this application) determines the direction of rotation of themaster wheel 30, and I shall not enter into a full description of this particular part of the actuator in this place.

vThirst-. The tra naferhtechqknism.

Rotatablymounted on a. shaft rigid in.

the framework is a set of transfer gears=65.

Each of these gears has a setofilong teeth 66,-andshortteeth 67.- A seriesiof plates 95supported by two framework separate t in Fig. 3, which gear I shallxhereinafteruefer to as the first transfer 'gear,.is.'in a. ositionto have its. short teetlr engage =bycarrying'teeth-21 of the carryi gear 20 iirengagement with the master w eel; The

long teeth 66.- of this first-transfer gear 65 engagewitlr-the nextcarrying gear-20.130 the left. The carrying teeth 21 ofthis sec ond carrying gem-engages thexshort teeth 67 of the second transfer gear 65, whose long teeth 66 engage the next carryinggear,

to the 'left. This arrangement continues through the entire length of the totalizer,i

carrying gears 65 being suflicientin number to accommodate tho-widest totalizer used on the machine. the totalizer moves relatively to the actuating mechanism, and hence relativelyi to the transfer gears'whic h are rigid in .the same frmnework. Consequently all the carrying gears 20 to the left of the master wheel in any totalizer engaged by the master wheel 30 have associated with them a transfer ear 65. and if the rotation of the master w eel 30 entails any carrying there will be a carrying chain extending through that portion of the totalizer which is to the left of 'the master wheel. i p f Numbers are inserted in the totalizei' one digit at a time, beginning with the digit in the higest order. Since any carrying gear 20 to the right of the master wheel 1s m a lower order than the digit which is being inserted, such carrying gears 20 need have no transfer gears with them for they are never moved during such insertion. As the totalizer progresses from right to left, during the insertion of the digits of the number, the carrying chain of course becomes continually longer as additional transfer gears 65 are engaged by the totalizer as it moves step by step to the left.

The arrangement of the transfer ears just described entails several difiicu ties.

pillars 96 rigid 1n the; ese transfer gears 65, from each other, thus preventing-motion of shows clearly the lateral relation It will be remembered that.

First, owing to the spiral .efl'ect always presout when carrying is done through a chain of transfer gears, the motion of the totali'aer gears 20 through the transfer gears may .be interfered with, as it is necessary for these transfer gears to be alined into their proper position before the carriage escapes.

Second, owingto the fact of the transfer gears and the. carrying gears of the totalizer beingrclatively movable to each.- other, it is practically impossible to provide the carr inggewrs 20 with a locking surface such as is shown in the'carrying gears of the cited patent to Wahl for instance.

7 Third, assuming the totalizer to have a 9-in the-decimal place in contact with the master wheel and assuming that one wishes to-snbtractthis 8' from the totalizer thus brhlg'ngthe-totalizcr to zero, it is possible toinicve the first'transfer gearyend perhaps someof the others, to the lcft'by a. violent manipulation of the 9 key. This is because rotation of the carrying gear 20, engaged with. the master wheel back to its zero posiwill bring'the carrying tooth 21 associii'ted with said gee-r41 to contact with the first'transf er gear. ow, if there is any lost motion between the master wheel and the carrying gear 20 engaged with it, the carryin tooth 21 will give the first transfer gear-allflow' and this blow may be communicated through the entire carrying chem to the left, since b hypothesis, all of the gears 20 to the left, eing in their zero position, have theircarrying teeth 21 in contact with a transfer car 65. Therefore it is neces sary to rovide mechanism to avoid the d fiiculties ust mentioned, and such mechanism I shall now. proceed to describe.

First, mechanism to remove the spiral effect occurring consequent to the operation of the transfer gears is as follows:

.Pivoted in the framework at 68 is an aliner cam 69 which has a cam surface 70 adapted to cooperate with all the transfer gears (best shown in Fig. 4). A spring 9 T tends .to rotate the cam 69 in a clockwise direction. The cam surface 7 0 is adapted to enter between the teeth of the transfer gears 65, which have deeply cut teeth (Figs. 2, 4, 6 and 7) and thus aline them. This cam surface 70 is made somewhat in the shape of a wed e, for when there is a spiral efiect, the displacement between two adjacent gears is small compared to the displacement between the gears at the beginning and the end of the chain.

The aliner cam 69 has rigid with it an arm 71, which is connected by a link 72 to the master dog 47. Consequently during the movement of this master dog the aliner cam will be entirely withdrawn from the trans fer. Is; On its return to its normal positionit will first engage the'seeond transfer 1 ,ssases geamounting frem'the right (shown hestin F1g.; 4)., then the nest. and s ona he gear on the extreme left being engaged ast.

the first transfer gearcann t b much out of RS position, the action of the cam-'10 on these gears will bring them into the proper.

Fig. 2. The carriage then es ap s .t the next decimal place.

Second, I shall now des ribe the nwansof reventing overthrow of th transfer gears.

Cooperating with the first and :s uenl arbitrarily selected transfer-gears is a series of cams 7 9. These are rotatably mounted on a shaft 80, rigid in the framework, and are held in their normal positions as shown in Fig. 2 by springs 81. Considering for the present but one, of. these cams, the one asso; ciated with the first. transfer gear. *65 as shown in Fig. 2, it will be seen that'it is provided with two notches 82 and 83, and that these notches are so spaced that movement of the cotijperating transfer gear 65 in eith r direction will result in a displacement of the cam as shown in Figs. 6 and 7.

Inspection of these figures shows that if the transfer gear 65, shown Fig. 6, for instance, is rotated in a clockwise direction, the long teeth 66 will displace the cam 79 until the tooth is free from the notch 82. However, since the surface of the cam -7 9 to the left of this tooth hasno notch, it will be impossible for the transfer gear (.35 to rotate another tooth until the cum 7 9 has been returned to its normal position by means of the spring 81. By the time this .has occurred, any momentum which the transfer gear 65 may have had has been destroyed. Therefore it is in'ipossible for this transfer gear 65 to move more than one tooth until the cam 79 has been returned to its normal position. Preventin r the transfer gear .65 from moving more t inn one tooth will revent the carrying gear '20 of the totahzer in mesh with it from moving more than one tooth, also, and since in. any totalizer, no gear to the right of the master wheel is required to move more than one tooth for a single actuation of the master wheel, thus limiting of the motion of these cars to but one tooth will not interfere wit the action of the totalizer.

Third, I shall now describe mechanism for preventing motion of the first transfer gear when a carrying tooth 21 is violently brought into contact with such transfer gear, and does not pass through it tooarry.

Fnlcrumed in the framework at 73 is a pair of arms 74 and 75 connected by a rigid post 76, and supporting between them at their upper ends a roller 77 adapted to engage with the first transfer gear 65 (Figs. 2, 3 and 4). Between the lower ends of these arms74 and, '75 .is-sqpported, a roller 78 adapted to contact with .the tooth of the mister wheel 30.. ,By reference to"Fig.'2, it will be seen that the master} wheel 30, its engaged carryinggear and-the first transfer gear 65,. fo rnra cham ofjrgearingyjand that the rollers Wand? are so lacedfthat rotation ofthe i iasteif wheehwi 1 result in oscillation of th framejwo'rh consisting 'of the ariusfifiia I 'New w11eq,u carryjngrtooth 211s brought into .colntla ,ct,' \iiit li lonel'of the teeth bf; the first transfer gear; the inas'teriwheeljfiwb'y r t wt i stepp d sthrds h 1.1m

5 I consi er the above described mechanism very important, since while in normal operation if the totalizer be brought to zero, no tendency ofthe first transfer 'gear to move will be, observed,'yet it isalways possible 40 by bringing the 'gear20'toit's normal position with great velocity to give a blow on the first transfer gear, and this blow will be communicated to the transfer gears to the left, and mnse'queiitl the totalizer may be madeto overthrow'ifithe mechanism just described is not present. L

While I have described this action as occurring when the totalizer is brought from 9 to zero; itfis obvious that it is resent in a lesser degfieqwhen the totalizer lS- brought from 8, 7 or even 6. Thenecessary condition for giving a hard blow is that the carrying gear 20 be moved a distancosufiicient to acquire considerablecmomentum before its sscarrying tooth makes contact with the associated gear. f

The same cfi'ect may also be observed when the totalizer stands, for instance, at 99999990. and a 9 is added into the totalizer.

As in the previously recited case, the addition of this last number will bring all the carryin teeth 21 in contact with their as sociatc' transfer gears (but on the other side of the teeth) and the same effect ma rotate be observed in a reverse direction My mechanism just described completely [overcomes this fault; since vif the master vwheel is sto ped with a tooth in 'ontacfwith the r0 en 78, it is'impossible for the hath-ansfer gear to move hence' forfanyfirans fer gears to the left theredfto be 'distui bed'from their normal position FourthGene1-aZiope r-ati0n'= I Having h e rib doth tm hii e sstall, I shall now describe;its enerhl. beration. 7

The totalizers are supported on the truck 12, which is rigid with the carriage otthe typewriter; Operations of the numeral keys actuate the typewriter ies'capen'ient; in the well known way, and thus the. carriage and the totalizers mounted on the truck 12 move step by step to the left as the} nume'rall keys are operated.

All of these actions occurdurin the first partof the operation of the key during the time that the attached cam 33 is moving'from' theposi tion shown in Fig. 2, into the position in which the right side of the slot 57 is in engaaement with the pin 56. At this timetho roller 36 of the rock shaft has reached the concentric surface of the cam 35.

2) Further motion of the key r'esults in the movement of the gooseneek 55 in a counter clockwise direction thereby rotating the sector 43 and the master wheel 30, which at that time is geared thereto, a number of teeth depending upon the numera1key operated. During this time, if any carrylng is done, the carryingteeth 21 of the gear 20 will engage the first transfer gear 65, and rotate it through the space of one tooth as said.

tooth 21. passes through said gear. Other rotation of the first transfer ear 65 is prevented by action of the cam 9 on the long teeth 66 as previously described. 7

(3) As the numeral key is further do pressed, the roller. 36 which has been riding on the dead'surfacc of the cam snaps back into its normal position by the force of a spring 100 (Fig. 2) attached to an arm 101 rigid with said roller 36, thereby restoring shiftiu l the eerryiu ears 20 ene step e the it weer the e W e 1 mie'fr gear atthl at; at tliefiotalizer, and bri n in the new cerryinfiegr 202mm met whee r tlfe return the 111, rd

I am ziivare'thet it has been proposed to make a jm'mmon carrying mechanism 00- operate with a number 'o'f-tota'lizers arranged in a. line, one for instance being that sholvu in the prior art. I wish to point out, however, the advantages that my structure has ever prior structures. By making the-carrying mechanism stationary, and the totalizers movable, I am able to dispose of the cumbersome corl connection shown in certein prier pa texite.

The more complex eleme t its-fixed t0 the remeand 't herehy avoids the-necessity of'rnbvi i'g this complex element synchronously with the carriage and carrying the key conneetien to this complex element.

Again, the form in which numbers are written on "the erk sheet is determined bv the-relative ;position of the totelizers to eaeh other.
